not limited ,to the exact details of construction shown and described, as it is obvious that various modioations thereof will occur to persons skilled in the art.

ln said drawings: Figure l is a top plan view of an underframe .embodying the fea-v tures of the present invention, approximately one half of the structure being broken away for the saving of space. Fig. 2 is a longitudinahrertical, section therethrough taken on the plane indicated by line 2-2 of Fig. l. Figs. 3 and e are transverse vertical sections taken respectively on the planes indi cated by lines 3-3 and 4me of Fig. 1. Fig. 5 is an end view. Fig. 6 is a fragmentary top plan of a portion of one bolster and connected. parts shown on an enlarged scale. Fig. 7 is a transverse vertical section therethrough taken just outside the bolster. Fig. 8 is a side elevation thereof. Fig. 9 is a view similar :to Fig. 6 of one of the cross bearers and connected parts. Fig. l0 is a transverse section therethrough talren just outside the cross bearer. Fig. ll is a side elevation thereof. Fig. l2 is a view partly in elevation and partly in transverse vertical section of a slightly modified embodiment.

Referring to the details, l' A are the center sills, B B the side sills, and C the end sill.. "llie side and center sills are connected by the usual tie bars D, cross-bearers E, and holsters F.

Sills il. are provided with a cover plate l and are trussed with a downwardly opening channel truss member 2 spaced at intermediate points from the'center sills by struts 3, each comprising an I section tapering from its upper edge to its lower edge and having its upper ilrnigesl ri vetcd to the lower anges of the center sills, and 4its lower flanges riveted to the web of truss member Q, a strut 3 bei-ng provided ust inside each cross bearer Specification of Letters Patent.

therefrom. Each of the sills A is preferably an outwardly openingchannel which extends into bolsters F and terminates outside the diaphragms of said bolsters, as at 6 6, each of said bolsters being of the builtup type comprising the usual top and bottom cover plates and fixed to the diaphragms and bridging the space between the center sills, the top cover plate being extended across the upper surface of the cover plate l of the center sills.

Draft sills 4:-4 are formed separately from the center sills and have their inner ends abutting against the respective ends of the center sills, and are connected thereto by splice plates 5-5 and by the flanges of the truss member 2. The cover plate 1 of the center sills is extended beyond the ends of the .center sills and is fixed to the upper lianges of the draft sills for strengthening the connection between t-he draft sills and the center sills. The forward edges of the bolster cover plates are also extended and are riveted to the upper and lower flanges of the draft sills for further strengthening the connection between. the draft sills and center sills. Truss member 2 ext ands upwardly on an incline at its end portions outside of the struts 3 to a point intermediate the width and between t-he center sills A and extends thence outwardly, and approximately horizontally through the respective holsters F to the outer end of the splice plates 5.4 The flanges of the channel 2 are riveted to the web of the draft and center sills throughout the length of the splice plates, the rivets also of course extending through the splice plates which are disposed between the respective channel flanges and sill webs.

It is to be noted that the web of the end portions of the channel truss member 2 spans the space between the center sills and between the draft sills, and the connection of the flanges of said member 2 to the webs of the draft sills as well as to the webs of the center sills, in addition to connecting the draft to the center sills, affords lateral stiffening inea-ns for said. sills and aids in obviating lateral separation thereof.

Each cross bearer E comprises upper and lower stress members 7 ably formed of a channel, 'the former opening upwardly and -the latter downwardly.

i E and preferably spaced a short distance and 8, each prefer- Upper member 'l' has its web rivetedintermediate its length to the flanges of sills A and to Ithe cover plate thereof, and at its ends' it l flanges are riveted to plates 9-9 which extend downwardly and are riveted to thef flanges of member 8, the outer end of each plate 9 beingA bent and riveted to the web of the respective sill B, the plate being cut away at its lower outer corner for accommodating the lower liange of the side sill. This is 'true when an inwardly opening channel side. sill is em ployed, but it is ofy course obvious, as seen in Fig. 12, that a side 'sill B may be employed of Zl section, in which instance the sill seats olf all cross members will ybe adapted to conform to the section of the sills. The lower member S of each cross bearer E extends beyond plate 9 and beneath the lower flange of side silll) and has its webriveted thereto. The web of/mem ber 8, intermediate the length thereof, is riveted to the lower flanges of the sills A. Members 7 and 8 are also connected by channel struts 10-10 intermediate their length between the side andcenter sills, each strut sustaining a nailing strip bracket 11.

l hat l claim is:
